Fans of DragonFly BSD will be getting their Christmas present late this year, and plans for 1.5 have been announced. MP safe networking code, the long awaited cache coherency management system, and a port of Sun's ZFS. Read here for more. Update: Refresh, empty cache, whatever, and check the shiny new beastie icon! And there was much rejoicing. Can we now please discuss DragonFly BSD?

I did for quite a while, but because of the problems they were having with the FreeBSD 4.x ports collection, I stopped using it for day to day things because it was a real PITA to get some of the programs I tend to use (like MPLayer for example).

A lot of work has gone into making most of the packages available in NetBSD's pkgsrc work natively under DragonFly, and as soon as everything I want/need is available again, I plan to go back to using DragonFly for most of my day-to-day needs.

Up until just after 1.2 was released, I had used it almost exclusively and had no crashes, performace was not noticably different from FreeBSD (that is to say it didn't seem faster or slower, and no, I didn't benchmark anything), and except for the 3rd party software situation that arose as DF moved away from FreeBSD 4.x compatibility, it was a really solid system.
